STAMPING MACHINE.

Application filed December 22, 1923. Serial No. 682,193.

To all whom it may concern:

Be it known that I, OSCAR -M. PANNIER, a citizen of the United States, residing at Ben Avon Heights, in the county of Alles gheny and State of Pennsylvania, have invented certain new and useful Improvements in Stamping Machines, of which the following is specification.

This invention is for a machine for embossing characters on sheet metal, and constitutes an improvement on a machine for a similar purpose of the type shown in Patent No. 1,049,908 of January 7, 1913, to

lVilliam J. Pannier, J r.

5 In machines of the type shown in said Letters Patent, the several master wheels are carried on separate hollow shafts, and each shaft has an operating handle thereon. Such an arrangement is expensive to manufacture, especially where more than four master wheels are employed, and the arrangement of handles is confusing to the operator, particularly where there are several more than four wheels.

The present invention has for its principal objects to provide a machine of this kind which is much more simple and wherein the operating handle maybe carried directly on the master wheel which it 0p ::0 \-rates.

The invention may be readily understood by reference to the accompanying drawings, in which:

Fig. 1 is a side view of the improvedmachine, with one of the side plates removed;

Fig. 2 is a top plan view of the machine;

Fig. 3 is an elevation looking toward one end of the machine;

Fig. 1 is a transverse section in the plane of line IVIV of 1;

Fig. 5 is a detail view of a hold ng a h empler d e insure the pro-Pe t e nins of h m s ng heels nd t nin he p r n h p si io hich theyare moved;

Fig. 6 is a side view of the top part of the machine, showing the openings through which articles to be stamped are passed.

In the drawings, 5 designates a base of suitable size on which are mounted two parallel par P ate 6 an 7 which are held in place by suitable bolts 8. In the plates are registering horizontally elongated slots 9, through which blanks to be stamped may be passed. A table 10, having an opening 11 therein, extends through the slots and is supported from one of the plates by a bracket 12. On this table is an adjustable guide member 13 which is adjustably held in position by a bolt 14 and wing nut 15.

In the plates above the slots are alined holes 16 through which the ends of a shaft 17 pass. The ends of this shaft have nuts 18 threaded thereon, and, as the part of the shaft between the plates is of increased diameter, this shaft, with the nuts 18, firmly holds the tops of the plates in proper spaced relation. Carried on this shaft are a plurality, four being illustrated, of wheels 19 having a plurality of projections or gear teeth 20 thereon. In these projections are cut recesses or matrices corresponding to the characters to be embossed.

In the shaft 17 are diametrically extending holes 21, there being one hole for each wheel, with the wheels positioned directly over the respective holes. In each hole is a spring 22 having a ball 23 adapted to be yieldably urged into recesses 19 of wheels 19. These balls and springs provide re leasable holding or ratchet means for the wheels, and the number of notches 19 are equal to the number of projections or teeth 20.

Passing through alined openings in the lower part of the plates 6 and 7 is a shaft 2 1 having an eccentric cam 25 thereon which is between the two plates. On the projecting end of this shaft is an operating handle 26, by means of which the eccentric may be partially rotated.

Riding on this cam is a yoke member 27 having its vertical arms 27 guided in and received by vertical grooves 28 in the in-' er fac s of th two p t 6 and Corrnecting the upper ends of the arms of the yoke is a, shaft 29 in vertical alinement with shaft 17. This shaft carries a plurality of type Wheels 36 similar to matrix wheels 19, but having embossing type on the teeth 30 thereof instead of recessed type, as in the upper wheclS. The lower wheels are in line with the upper wheels, and the tops of the upper wheels extend into the opening 11 oftable 10.

The wheels 30 may also, have ratchets, similar to those illustrated in Fig. 5 and described above, associated therewith, such ratchets being designated 81.

The wheels 19 and 30 have a corresponding series of characters thereon, preferably numbers, and the series of characters are so arranged that, as both wheels are rotated in the same direction, the same distance, corresponding type and matrix characters are opposite each other.

For rotating both wheels in the same direction to the same extent, a plurality of master wheels 33 are provided, one master wheel for each pair of embossing wheels. These wheels, which are in the form of internal gears, have teeth 34 that mesh with the teeth of the embossing wheels, and the master wheels are rotatably supported on arcuately curved concentrically arranged bearing plates 82 between the upright plates 6 and 7, the internal teeth having a bearing on these arcuate members, as clearly shown in Fig. 1.

Upon movement of the different rings, difierent pairs of embossing wheels will thus be rotated. Each master wheel has a handle 35 thereon projecting radially therefrom, and the handles of the respective wheels are made of different length, as shown in Fig. 2, to enable the use of knobs 36.

Secured across the front of the plates 6 and 7 is a transverse plate 37 whose top forms a stop to limit the movement of handle 35 in one direction, as shown in Fig. 1. hen the handle of any master wheel is against this plate, the blank teeth of the embossing wheels operated by it are opposite. As the handle is moved away from the limiting plate, the embossing wheels are rotated to bring corresponding characters on the embossing wheels opposite each other. By reason or" the ratchet mechanisms, the advance of diiierent characters to embossing position can be noted. Furthermore the peripheries of the master wheels are provided with peripheral markings, as indicated at 38, corresponding to the characters on the embossing wheels. As each handle 35 is moved away from plate 37 the character which will be impressed is indicated by the character which appears in the window 37 in the plate 37.

In operation, the various handles are adj usted to impress the desired marking, after which a metal tag or other article to be marked is positioned on plate 10. Lever 26 is then moved down from the position shown in Fig. 1, rotating cam 25, which raises yoke 27 and consequently shaft 29 with the type wheels 30. The type wheels, rising through opening 11 in the table into the pressing engagement with the upper matrix wheels 19, the tag or other article to mama.

be marked is embossed according to the position to which the marking wheels have been turned. The type wheels do not entirely disengage the teeth of the master wheel when so raised.

Upon moving handle 26 in the reverse direction, the yoke is free to drop back into normal position. A leaf spring 39, as shown in-Fig. 1, may be provided to urge the yoke down.

The ratchet devices described insure the positioning and holding of the embossing wheels in proper registering position dur ing the operation of embossing.

By increasing the diameter of the. master wheels, the machine may be readily made to operate upon metal tags of larger dimensions. Any desired number of embossing wheels may be used.
